Answer:
#1 is x+23°=23
#2 is x+61°=61
Explanation:
Because when you are adding it will always be a positive number
But when you are subtracting it will always be a negative number
x=48
Since these angles are supplementary, they add up to 180. so, you can set the equation x+23+x+61=81. Simplify the equation and solve for x
